Cerro Flow Products Llc 1546 Type L Hard Copper Tube

Product Description

The CERRO FLOW PRODUCTS LLC 1546 is a Type L hard copper tube sold in a 10-piece pack, with each length measuring 3/4 inch diameter by 5 feet. Type L copper is recognized by its blue markings and features a wall thickness that sits between the lighter Type M and the heavier Type K, making it the standard choice for residential and light commercial water distribution, HVAC refrigerant lines, and hydronic heating systems. The hard-drawn temper means the tube holds its shape under pressure and requires no additional support over standard spans. Licensed plumbers and HVAC technicians install this tube using sweat, press-fit, or compression fittings in accordance with applicable plumbing codes.

This tube is suited for above-ground and in-wall potable water supply lines, hot and cold domestic plumbing, radiant heating supply and return runs, and refrigerant piping in split-system and commercial HVAC applications where Type L is specified by design. The 5-foot cut length is practical for rough-in work, fixture drops, and short branch runs where full 10-foot or 20-foot sticks would require additional cutting and handling. The 10-piece pack provides enough material for a typical residential rough-in or a service technician's truck stock.

Key Features

• Type L wall thickness meets ASTM B88 standards for residential and commercial pressure service
• Hard-drawn temper maintains dimensional stability without annealing or additional bracing
• 3/4 inch nominal diameter suits standard residential water supply and HVAC branch lines
• 5-foot length reduces waste on short runs and fixture connections
• Sold as a 10-piece pack for job-site or truck-stock convenience

Compatibility

Designed as an OEM-style replacement and standard-stock copper tube compatible with sweat, press-fit, and compression fittings sized for 3/4 inch Type L copper tube in residential and commercial plumbing and HVAC installations.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician in compliance with the International Plumbing Code (IPC) and local amendments. Shut off the water supply and relieve system pressure before cutting or joining existing lines. Use a properly sized tube cutter to produce a clean, square cut, and deburr the end thoroughly before applying flux and fittings. Avoid open-flame work near combustible materials, and allow joints to cool fully before restoring pressure.
